Superachromatic circular polarizer
Measurement Science and Technology, 2000We present a design for a superachromatic circular polarizer that can be constructed with conventional, two-element, achromatic half-wave and quarter-wave retarders and used over the whole range of visible wavelengths.

Circular-polarization modulator
Nature Photonics, 2017Switching the handedness of circularly polarized light requires separately controlling the phases of orthogonal components while maintaining their magnitudes, ideally with gigahertz operation rates. Ultrafast switching has now been realized via all-optical control of birefringent metamaterials.

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1998
Abstract Novel LCD, which transmits circularly polarized light, is reported. The circular polarized light enables us to see the LCD screen through polarized sunglasses. It is developed for outdoor application, such as mobile computing, car navigator, and so on. The circular light is achieved by placing additional quarter wave film upon the screen.

Circular polarization memory of light
Physical Review E, 2005Circular polarization memory of light multiply scattered by Mie particles is investigated. The mechanism of randomization of helicity is found, in general, to dominate light circular depolarization by particles of large size or a high refractive index while the mechanism of randomization of direction dominates for small particles of a lower refractive ...

Circular Polarization Array Antenna
2008 Asia-Pacific Microwave Conference, 2008A 4 by 4 circular polarization microstrip square patch array antennas based on quarter-wave impedance matching and T-junction power divider were designed, simulated, fabricated and measured. The patch type used to generate circular polarization is corner-truncated square microstrip antenna.

Directed Circular Polarized Antenna
2018 XXIIIrd International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED), 2018The goal of proposed research is to construct the circular polarized narrow-band directed antenna using low-loss dielectric and high relative permittivity material for the substrate. Presented first part contains the simulation of such antenna using the software which based on Finite Element Method for the purpose to fined optimal parameters of such ...

TEM Modes and Circular Polarization
American Journal of Physics, 1963In this treatment of transverse electromagnetic waves circularly polarized waves of opposite senses are associated with a given positive frequency and the corresponding negative frequency. Linear polarization is thus obtained only as a superposition of circularly polarized waves.

Far-Infrared Circular Polarizer
Review of Scientific Instruments, 1964This paper describes several devices (circular polarizer, isolator, circulator) which will be useful for the manipulation of far-infrared radiation. These devices depend on the properties of a class of magneto-rotary solids which are operated at or near their cyclotron resonance frequency. Experimental results on the use of InSb as a circular polarizer

Circular Polarization of Internal Bremsstrahlung
Physical Review, 1957A calculation is made of the circular polarization of the internal bramsstrahlung in allowed $\ensuremath{\beta}$-decay with the most general $\ensuremath{\beta}$-interaction. The polarization is found to rise from zero at the low-energy end of the spectrum to a maximum value at the high-energy end. This maximum value depends critically on the relative
